Figure 4.1 shows a schematic band diagram of an illuminated idealized solar cell structure with an absorber and the semi-permeable membranes at two conditions. The quasi-Fermi level for electrons, EFC, and the quasi-Fermi level for holes, EFV, are used to describe the illuminated state of the solar cell.
The diagram illustrates the conversion of sunlight into electricity via semiconductors, highlighting the key elements: layers of silicon, metal contacts, anti-reflective coating, and the electric field created by the junction between n-type and p-type silicon. The solar cell diagram showcases the working mechanism of a photovoltaic (PV) cell.
Figure 1. Diagram of a photovoltaic cell. Regardless of size, a typical silicon PV cell produces about 0.5 – 0.6 volt DC under open-circuit, no-load conditions. The current (and power) output of a PV cell depends on its efficiency and size (surface area), and is proportional to the intensity of sunlight striking the surface of the cell.
Explore SuperCoaching Now The diagram above is a cross-section of a photovoltaic cell taken from a solar panel which is also a type of photovoltaic cell. The cell consists of each a P-type and an N-type material and a PN junction diode sandwiched in between. This layer is responsible for trapping solar energy which converts into electricity.
The bottom layer, the last one may completely be covered by the material in which the conductor is made up of. A photovoltaic cell works on the same principle as that of the diode, which is to allow the flow of electric current to flow in a single direction and resist the reversal of the same current, i.e, causing only forward bias current.
A typical silicon PV cell is composed of a thin wafer consisting of an ultra-thin layer of phosphorus-doped (N-type) silicon on top of a thicker layer of boron-doped (P-type) silicon. An electrical field is created near the top surface of the cell where these two materials are in contact, called the P-N junction.
Light shining the solar cell will produce both a voltage and a current to generate electric power . A typical schematic diagram of silicon solar cell is shown in Fig. 1. PV energy conversion in solar cells consists of two essential steps. First, a material in which the absorption of light generates an electron-hole pair is required.

Photovoltaic (PV) power generation is the main method in the utilization of solar energy, which uses solar cells (SCs) to directly convert solar energy into power through the PV effect. However, the application and development of SCs are still facing several difficulties, such as high cost, relatively low efficiency, and greater influence from external conditions. Among them, the …
